Adoption of Existing Socioeconomic Scenarios

Description

The UNEP Handbook describes an approach to developing sectoral assessments of impacts and adaptation.
In general, analysts are encouraged to use existing scenarios of both socioeconomic conditions and
climate change, to integrate them, and to develop adaptation strategies.

The definition of socioeconomic includes demographic and economic data, technology, legislation,
culture, decision-making processes – “everything that shapes a society.” Table 2.1
in the handbook lists relevant variables for each of the sectors covered (water resources, coastal
zones, agriculture, human health, energy, forestry, livestock and grasslands, wildlife and
biodiversity, and fisheries). Sources for data-based scenarios are given, and using multiple
scenarios is recommended. Specific guidance is sparse.

Appropriate Use

The Handbook can be used for analyses of sectoral impacts and adaptation to climate change.

Scope

Local, sectoral, regional, and national. However, sources for existing socioeconomic scenarios are
global and regional only, except for the World Bank, which includes countries.

Key Output

Scenarios that are either “borrowed” from the literature or “inspired” by
historical trends and geographical analogues.

Key Input

Qualitative and/or quantitative information on the sector of interest.

Ease of Use

Relatively easy, especially if literature sources are used instead of primary data gathering and
scenario development.

Training Required

No training required.

Training Available

No formal training currently offered.

Computer Requirements

None, although data may be downloaded from sources such as the World Bank and manipulated by
spreadsheet or other computer-based programs.
